Definitions
- the invention relates to a coke-heated cycle gas cupola furnace for the material and / or energetic utilization of waste materials of different compositions according to main patent P 196 40 497.
- the flue shaft of the cycle gas cupola which is flared from the loading hopper to the stove and consists of flared and / or cylindrical furnace sections, has in the area of the cycle gas and excess gas extraction level, there is a large-volume suction and gas calming ring chamber, which are connected by a furnace shaft part with a narrowing in cross-section and with a built-in oxygen direct injection lance directed obliquely to the melting and superheating zone.
- An additional gas vent is located below the hopper and a pipe socket for a viewing hole or for the installation of an additional burner is installed in the upper suction and gas calming ring chamber.
- the lower suction and gas calming ring chamber is directly connected to a solids supply lock, as well as an excess gas suction connection and one or more water supply devices.
- This arrangement and design of the individual furnace sections is intended to ensure an undisturbed process flow in the material and / or energy recovery of different feedstocks with different consistency and different softening intervals, in which on the one hand the gas velocities in the area of the two gas extraction levels and thus the clogging and dust deposits in the area of the Circulation gas and excess gas suction openings are reduced to such an extent that the unimpeded process flow even when using moist feed materials, such as domestic waste fractions, is guaranteed and process-specific temperatures of high 800 ° C no longer lead to harmful sintering phenomena.
- the local narrowing of the furnace shaft above the excess gas extraction level in the area of the oxygen nozzles enables the formation of a second, thermo-chemically active zone characterized by controllable oxygen supply and a longer residence time of the feed materials, thereby ensuring the controlled completion of all material-specific gasification and degassing processes of the feed materials can be realized before the fill further sinks.
- the cycle gas cupola furnace shown in the main patent P 196 40 497 can be used advantageously for the material and / or energetic utilization of waste materials of different compositions, but can be arranged by arranging the lower suction and gas calming ring chamber above the melt formed by the gas jet compressor.
- the present invention relates to a further embodiment of the arrangement of the lower suction and gas calming ring chamber on a coke-heated cycle gas cupola for the material and / or energy recovery of waste materials of different compositions according to main patent P 196 40 497, which do not yet completely cover the suction its basic constituents CO, H 2 , H 2 0, C0 2 as well as gaseous organics broken down into their trace components or already re-formed are reliably prevented.
- the furnace shaft which is flared from the loading hopper to the hearth, from the level of the melting and superheating zone down to the hearth area provides an increasing coke volume for the Bou ⁇ ouard reaction and thus ensures a higher effectiveness of this desired reduction reaction.
- an improvement in the reduction conditions compared to the oxides of the molten phases from the material and / or energy recovery of waste materials of different compositions is achieved, which in turn results in better metal and slag qualities.
- the arrangement according to the invention of the lower suction and gas calming ring chamber on a coke-heated cycle gas cupola furnace for the material and / or energy recovery of waste materials of different compositions will be explained in more detail using an exemplary embodiment.
- the accompanying drawing shows a longitudinal section through the coke-heated cycle gas cupola from the cycle gas level to the stove. It shows that below the charging funnel 1 begins a downwardly conically widened furnace shaft part 4, m the gas supply nozzles 3, which are inclined downward above the cycle gas suction plane 2 and are connected to the clean gas side of a gas industry (not shown) or a separate gas reservoir, are arranged.
- suction and gas calming ring chamber 5 which widens conically at the top available, which is delivered with the refractory material 10 and is coupled with a water cooling 6 for start-up and shutdown processes.
- This suction and gas calming chamber 5, which also has a pipe socket 7 for the installation of an additional burner and / or a viewing hole, and one or more cycle gas suction socket 8 with inspection opening 25, which are provided via pipes with integrated actuators, measuring devices for determining volume flow and compensation elements for pipe expansions , is connected directly to an oxygen-operated, water-cooled gas jet compressor 24.
- a cylindrical furnace shaft part 9 which is provided with the refractory material 10 to n in the area of the excess gas suction plane 11, and has one or more built-in oxygen lance 13 directed obliquely to the melting and superheating zone .
- the furnace shaft part 9 is connected at the bottom in the region of the excess gas suction level 11 with a large-volume suction and gas calming ring chamber 12.
- a water supply device 15 In the ring chamber 12 or alternatively in the excess gas suction nozzle 14 there is a water supply device 15 and above the water supply device 15 a supply lock for solids 16 with two gas-tight locking devices 17; 18 and a thrower 19 installed.
- the excess gas suction connection 14 is connected via a delivery element, not shown, to a gas industry, also not shown, which in turn is optionally connected to the gas supply nozzles 3 on the clean gas side.
- the gas jet compressor 24 merges and the furnace shaft 20 continues as a truncated cone that widens conically downwards and merges below the annular chamber 12 m with a cylindrically shaped and supplied hearth 21 in which the exhaust openings for the molten metal 22 and liquid slags 23 are installed.
- the procedure described below is to be followed.
- the genus consists of 26.7% shredded domestic garbage (I), 31.6% bulky garbage with one
- the set weight is 1000 kg.
- the furnace is equipped with 6 circulating gas emitters and has a capacity of 7.50 t / h feed materials. It is prepared like a coke-fired oven. After the full coke has been introduced, the furnace is closed and burned with an auxiliary burner and natural draft with the flap closed in the circulating gas and excess gas line over the emergency chimney. After the full coke column has burned through, it is blown down to white heat using oxygen and air. The air opening on the gas jet compressor 24 is closed and the flaps m of the cycle gas and
- a gas vent 27 is provided above the sealing gas supply for the evaporation products that arise when a sealing gas of higher temperature is used, which is connected to the gas industry and through which these evaporation products directly Gas industry can be supplied. Since the processes in the furnace are temperature-dependent, approx. 50% of the amount of process gas generated in the conical shaft 26 between the excess gas suction level 11 and the circulating gas suction level 2 and the rest through the combustion and thermochemical material conversions in the melting and superheating zone, ie primarily through combustion of the solid carbon potential educated. 8693 Nm 3 / h are withdrawn as excess gas and fed to the gas industry, which includes a disintegrator. The temperature of the gas is 550 ° C.
- the gas leaving the disintegrator at approx. 35 ° C consists of approx. 36% H 2 , 4.6% N 2 , 15.3% C0 2 , 42% CO and 3.1% H 2 0. About 359 1 / h of water condense out. Furthermore, approx. 800 kg / h molten metal and 1660 kg / h slag, which meet the requirements of use as a building material. After gas cleaning, there is a purified fuel gas with an energy equivalent of 19.48 MW. In addition, approx. 40 kg / h disintegrator sludge and 0.8 kg / h loaded activated coke.

Abstract
L'invention concerne une variante de l'agencement de la chambre annulaire d'aspiration et de calmage au gaz sur un cubilot à circulation de gaz chauffé au coke, pour la valorisation matérielle et/ou énergétique de matériaux de déchets de différentes compositions selon le brevet principal P 196 40 497, agencement avec lequel l'aspiration de produits organiques gazeux n'étant pas encore complètement décomposés en leurs constituants de base CO, H2, H2O, CO2 ainsi qu'en leurs composants à l'état de traces, ou bien déjà reformés, n'est pas empêchée de façon sûre. Cette aspiration est empêchée de façon sûre par le fait que la chambre annulaire inférieure d'aspiration et de calmage au gaz est disposée en dessous, de façon qu'elle aille jusqu'au plan de la zone de fusion et de surchauffe formé par le compresseur à jet de gaz. Avec cet agencement, le gaz en excès est extrait de la cuve de four directement de la zone de fusion et de surchauffe, à des températures élevées d'environ 2000 °C. Le gaz en excès est également guidé à travers la couche de coke incandescente de la zone de fusion et de surchauffe du cubilot à circulation de gaz chauffé au coke. Grâce à l'effet consommateur d'énergie de la réaction de Boudouard, le CO2 est transformé en CO avec abaissement de la température du gaz. Simultanément, l'élimination du gaz en excès contenu dans le gaz de processus se fait selon la technique des fluides.
